| Abstract: | Ground settlement of roadbed widening project in highway extension construction is analyzed by non-linear FEM numerical calculation. Based on field testing of physical and mechanical parameters of engineering materials, the excavation methods of roadbed slop, fill-up technologies and widening width of roadbed are simulated and analyzed, and their influence on roadbed settlement are obtained. The results can be expected to be a reference to similar engineering construction. |
